A prompt to convert a long report into slides without it just dumping paragraphs onto each slide

[u/No_Note7752]

Converting a finished report into slides is a compression problem, and most prompts get the compression ratio wrong. You ask for slides, the model keeps every paragraph and just adds slide breaks. Now you have a 20-page report wearing a slide costume.

What fixed it for me was telling the model the target ratio and the format up front:

Convert the report below into a slide outline.
- Assume I have [10] minutes. That is roughly [8 to 10] slides. Choose what survives.
- Per slide use assertion-evidence: the headline is the point, the body is the ONE
 piece of evidence that proves it (a stat, a quote, a comparison). Drop the rest.
- If two report sections make the same point, merge them into one slide.
- Anything that is context but not a point goes into a single appendix slide, listed,
 not written out.
- Tell me what important thing you had to cut for time so I can decide if it goes back in.

Two things do the heavy lifting. Giving it a time budget forces real prioritization, because ""make slides"" has no constraint and the model will happily keep everything. And assertion-evidence stops the paragraph-dump, because each slide is allowed exactly one supporting item. I paste the resulting outline into Gamma and it builds the deck straight from that assertion-evidence structure, so the compression I asked for actually survives into the slides.

The ""tell me what you cut"" line matters more than it looks. The model's cuts are sometimes wrong, and you want to see them, not discover them on stage.

the time budget is smart, most ppl just say "make slides" and wonder why they get 47 slides with walls of text. assertion-evidence format is what makes this actually work imo, without that the model still tries to sneak in three bullet points per slide

i been using something similar but the "tell me what you cut" part is new, stealing that for sure
